I have never seen a k46 with five bolt rims. Just a square key way and a circle clip. The K66 is the lightest Tuff Torq with a five bolt rim.
I was trying to put in a picture of this page but can't figure out how to do it. On this page it shows that my 09 Husqvarna LGT 2554 big box store "gardentractor" did indeed have the K-46. It also had five bolt wheels. I was really surprised when I figured that out. And not happy either.
Not trying to argue with anyone here.
Just hoping someone can learn from my disappointment. And that they can avoid the financial hit that comes with it.

I have since learned some models and brands actually have the tranny model listed in a sticker on the seat bottom!
